If you're concerned about braking, don't forget to add good tires to your list.
For what it's worth, I had my Blazer brakes installed for my first track day this last spring at Gingerman raceway. With cheap rotors from Amazon, "commercial duty" Wagner pads from Rock Auto, and 255 width racing tires I had pretty good stopping power lap after lap. Granted my car didn't have the beans to get much faster than 94mph, but in the braking zones I was consistently gaining ground on my buddy's '06 Mustang GT. His GT has bigger brakes and Hawk pads, but his tires were very worn out.
If all you're doing is "spirited driving" then I don't think you'll be disappointed with Blazer brakes. Especially if you use good components and decent front tires. Clamping force doesn't mean much if you're just locking the front tires into a skid!
